4L Vision

Ralph Suikat established 4L Vision in 2016 following the sale of his interest in STP Informationstechnologie, which he co-founded in 1993. The office serves as the central vehicle for his capital and forms the core of the 4L Impact Family, a network that includes more than twenty operating companies and partners. The investment approach targets impact opportunities that address defined social or environmental challenges. Allocations span private equity, public equity, fixed income, real assets, commodity investments and liquidity portfolios. Geographic exposure centers on Germany with additional activity in other European markets. Confirmed holdings include social housing projects and sustainable real estate portfolios in Germany and Europe, alongside an impact commodities book. Dr. Johannes Knorz serves as CEO and chairs the impact committee. Peter Brock acts as investment director. Alexander Raquet holds the commercial officer role. The team maintains memberships in Toniic, the Bundesverband Impact Investing and The ImPact. No operational events from the last twenty-four months appear in available records. The office structure integrates the family’s operating businesses and philanthropic vehicle Fairantwortung gAG under a single governance framework. Ralph Suikat holds the chair of the supervisory board for both 4L Capital AG and Fairantwortung gAG, creating direct oversight links between investment decisions and the family’s commercial and grant-making activities.
